lovebird health? good or bad?

[Sunnylovebirds]

i have a four week old lovebird that i am hand feeding. on the car trip from getting him he would stretch preen and look around. when i got home i placed him in his brooder. he nibbled on some millet that I'm weaning him on and went straight to sleep. he seems pretty healthy looking, but is that normal baby behavior? I'm new to babies oh and yes i know how to hand feed him:20:

p.s he isn't making a lot of noise, just chirps here and there. he is not fluffed him or anything. i think he is just a little scared
